[SCSI] qla2xxx: Clear error status after uncorrectable non-fatal errors.

Currently error status is cleared only after the uncorrectable fatal errors
in the qla2xxx_pci_slot_reset. This fix is added to clear the error status in
qla2xxx_pci_resume. This way for both fatal and non-fatal errors the error
status gets cleared properly.
